# This program may be used to create a /etc/shorewall/capabilities file for
# use in compiling Shorewall firewalls on another system.
#
# On the target system (the system where the firewall program is to run):
#
# [ IPTABLES=<iptables binary> ] [ MODULESDIR=<kernel modules directory> ] shorecap > capabilities
#
# Now move the capabilities file to the compilation system. The file must
# be placed in a directory on the CONFIG_PATH to be used when compiling firewalls
# for the target system.
#
# Default values for the two variables are:
#
# IPTABLES - iptables
# MODULESDIR - /lib/modules/$(uname -r)/kernel/net/ipv4/netfilter
#
# Shorewall need not be installed on the target system to run shorecap. If the '-e' flag is
# used during firewall compilation, then the generated firewall program will likewise not
# require Shorewall to be installed.
